Well, I've already tried those devices. I've read the man pages on everything I could find using apropos, so I have a reasonable understanding of the significance of the device naming conventions. As a desperate measure, I even wrote a script to tip(1) to all the likely devices in /dev, but to no avail. Interestingly, I installed the same distribution (bindist.?? from DOS floppies) on a 386SX, and had the same problem. I've used tip, echo and cat. From memory, I think echo and cat also claim that the port cannot be opened. It may be significant that the laptop has a PCI architecture. Regards, Casper.
